一、概述在石油供应日益紧迫的今天,世界上大多数国家,加快了煤的气化,液化技术的开发利用。联邦德国煤炭气化能力今后二十年气化煤的数量将从1985-1990年的200万吨,提高到2000-2005年的1,600万吨,用大量的发生炉煤气和液化气来取代石油及天然气。在煤的气化技术方面:多种煤的高压、富氧、加氢、高产的研究取得了较大的成就。在液化技术方面:常压溶剂法、中压溶剂萃取法、高压直接加氢法,也取得了显著的进展。其它方面的粉煤气化、油气混烧、油煤混烧都进入了工 I. Overview In the increasingly urgent oil supply today, most of the world’s countries to speed up the gasification of coal, liquefaction technology development and utilization. Federal German coal gasification capacity The quantity of gasified coal in the next 20 years will increase from 2 million tons in 1985-1990 to 16 million tons in 2000-2005 with a large amount of producer gas and liquefied gas to replace oil and natural gas. In coal gasification technology: a variety of coal high pressure, oxygen enrichment, hydrogenation, high yield of research has made great achievements. In liquefaction technology: atmospheric solvent, medium pressure solvent extraction, high pressure direct hydrogenation, also made significant progress. Other aspects of the pulverized coal gasification, oil and gas co-firing, coal-oil mixed into the work
